Description

This application claims priority from Chinese Patent Application No. 202010076893.3 entitled "WEARABLE DEVICE" filed with the State Intellectual Property Office of the People's Republic of China on January 23, 2020, which is incorporated herein by reference in its entirety.

This application relates to the field of wearable device technology, and more specifically, to wearable devices.

As the pace of people's lives accelerates, the number of patients suffering from abnormal blood pressure is increasing, and abnormal blood pressure can easily cause various diseases. Therefore, instant detection of blood pressure status is very important, and wrist-type blood pressure monitors have attracted attention. However, in existing wrist-type blood pressure monitors, the detection unit of the blood pressure monitor is directly connected to the air nozzle of the air bag. During the process of assembling or disassembling the compression band that houses the air bag, the detection unit is easily affected and displaced, which causes damage to the detection unit.

The present application provides a wearable device that avoids the problem of internal components of the wearable device being damaged by displacement of the compression band when assembling or disassembling the compression band, thereby extending the service life of the wearable device.

The wearable device provided in the present application includes a watch face, a watch band, and a compression band. The watch face includes a bezel, a bottom cover, and a blood pressure measurement assembly. The bezel is connected to a peripheral edge of the bottom cover and together with the bottom cover encloses a cavity in the watch face. The bottom cover is provided with an external plug connection port, a flow path, and an internal plug connection port that are in continuous communication with each other, the external plug connection port being closer to the bezel than the internal plug connection port. The blood pressure measurement assembly is housed in the cavity in the watch face, and an air nozzle of the blood pressure measurement assembly is in communication with the internal plug connection port. The watch band is connected to the bezel, the compression band and the watch band are stacked, and the air nozzle of the compression band is in communication with the external plug connection port.

In the wearable device exemplified in this application, the air nozzle of the blood pressure measuring assembly communicates with the internal plug connection port, and the air nozzle of the compression band communicates with the external plug connection port, and communication is achieved between the air nozzle of the blood pressure measuring assembly and the air nozzle of the compression band using a flow path. That is, this flow path separates the air nozzle of the compression band from the air nozzle of the blood pressure measuring assembly, and the blood pressure measuring assembly is not easily affected and displaced during the process of assembling or disassembling the compression band. This helps to extend the service life of the wearable device by avoiding the problem of the blood pressure measuring assembly being damaged when the compression band moves.

Furthermore, in the wearable device exemplified in this application, the external plug connection port, the flow path, and the internal plug connection port are all integrated in the bottom cover of the watch face, so there is no need to place the communication piping in the cavity in the watch face. This reduces the space used by the communication piping in the cavity in the watch face, promotes the expansion of the space utilization in the cavity in the watch face, realizes a lightweight and thin design of the watch face, and improves the elegance of the appearance of the wearable device.

Furthermore, in the wearable device exemplified in the present application, the external plug connection port is closer to the bezel than the internal plug connection port, i.e., the external plug connection port communicating with the air nozzle of the compression band is closer to the edge. The air nozzle of the compression band can communicate with the air nozzle of the blood pressure measurement assembly without extending directly under the blood pressure measurement assembly. The extension length of the compression band under the watch face can be reduced, which promotes the reduction of the overall thickness of the wearable device and the realization of a lightweight and thin design of the wearable device. Furthermore, the position between the compression band and the blood pressure measurement assembly can be more flexibly arranged, and components such as the battery and the heart rate detection sensor located in the cavity in the watch face can be more flexibly arranged. This promotes the expansion of the space utilization of the cavity in the watch face and the realization of a lightweight and thin design of the watch face.

The bottom cover is provided with an internal plug connection nozzle and an external plug connection nozzle, the internal plug connection port is formed inside the internal plug connection nozzle, and the external plug connection port is formed inside the external plug connection nozzle. The air nozzle of the blood pressure measurement assembly is in communication with the internal plug connection port. That is, the air nozzle of the blood pressure measurement assembly and the internal plug connection nozzle are plugged with each other, specifically, the air nozzle of the blood pressure measurement assembly is plugged with the internal plug connection port, or the air nozzle of the blood pressure measurement assembly is connected with the internal plug connection nozzle by a sleeve. Similarly, the air nozzle of the compression band is in communication with the external plug connection port. That is, the air nozzle of the compression band and the external plug connection nozzle are plugged with each other, specifically, the air nozzle of the compression band is plugged with the external plug connection port, or the air nozzle of the compression band is connected with the external plug connection nozzle by a sleeve.

The compression band includes a cuff, an air bag contained in the cuff, and an air nozzle in communication with the air bag.

The air bag and the air nozzle are integrally formed, or the air bag and the air nozzle are formed by assembly.

In one implementation example, the cross-sectional area of the flow path is greater than or equal to 1 ^mm2 , thereby suppressing air resistance in the flow path, ensuring the air exchange speed between the air nozzle of the compression band and the air nozzle of the blood pressure detection assembly, realizing high-speed air circulation between the air nozzle of the compression band and the air nozzle of the blood pressure detection assembly, and improving the blood pressure detection efficiency of the wearable device.

In one implementation, the watch face further includes a top cover that is secured to the side of the bezel away from the bottom cover.

The top cover may be a display. The display includes a display surface that is spaced from the bezel, and the display surface is configured to display information such as the time, an icon, or a physiological parameter of the user.

In one implementation, the bottom cover includes a top surface facing the watch face cavity, and a distance between the external plug connection port and the top surface of the bottom cover forms a first distance range, and a distance between the internal plug connection port and the top surface of the bottom cover forms a second distance range, and the second distance range partially or completely overlaps with the first distance range. In other words, the external plug connection port and the internal plug connection port share part or all of the thickness distance of the bottom cover in the Z direction, i.e., the external plug connection port and the internal plug connection port are relatively close to each other in the Z direction. This facilitates reducing the distance in the Z direction between the compression band and the blood pressure measurement assembly and reducing the thickness of the bottom cover, thereby facilitating the realization of a lightweight and thin design of the wearable device.

The width direction of the watch face is the X direction, the length direction of the watch face is the Y direction, and the thickness direction of the watch face is the Z direction. Every two of the X direction, Y direction, and Z direction are at right angles to each other.

The Z direction is from the top cover to the bottom cover of the watch face.

The top surface of the bottom cover is parallel to the XY plane of the watch face.

The distance between one end of the external plug connection port and the top surface of the bottom cover forms one end of a first distance range, and the distance between the other end of the external plug connection port and the top surface of the bottom cover forms the other end of the first distance range.

The distance between one end of the internal plug connection port and the top surface of the bottom cover forms one end of a second distance range, and the distance between the other end of the internal plug connection port and the top surface of the bottom cover forms the other end of the second distance range.

In one implementation, a third distance range is formed between the flow channel and the top surface of the bottom cover, and the third distance range is a combination set of the first distance range and the second distance range, i.e., the distance between any position of the flow channel and the top surface of the bottom cover is always included in the first distance range or the second distance range. This allows the flow channel to always share the thickness distance of the bottom cover in the Z direction with the external plug connection port or the internal plug connection port, i.e., the flow channel does not occupy any additional thickness distance of the bottom cover in the Z direction, which facilitates the reduction of the thickness of the bottom cover and further facilitates the realization of a lightweight and thin design of the watch face.

In one implementation, the air nozzle of the blood pressure measuring assembly extends in the Z direction.

In one implementation, the flow path is hyphen-shaped, S-shaped, L-shaped, or Z-shaped.

In one implementation, the bottom cover includes a main body member and a first cover member, the peripheral edge of the main body member is connected to the bezel, the first cover member is fixed to one side of the main body member, and the first cover member forms an internal plug connection port and, together with the main body member, forms a flow passage by enclosure. This simplifies the process of forming the flow passage, i.e., simplifies the process of forming the bottom cover, thereby reducing the manufacturing cost of the bottom cover.

The main body components are made from plastics such as polycarbonate or metal materials such as stainless steel.

In one implementation, the main body member includes an upper surface facing the cavity within the watch face, the upper surface of the main body member partially protruding to form a boss, and the first cover member is fixedly connected to the boss and, together with the boss, forms a flow path by enclosure.

In the wearable device illustrated in this implementation example, the boss formed by partially protruding from the top surface of the main body member forms a flow path together with the first cover member. Instead of increasing the overall thickness of the bottom cover, it is only necessary to increase the thickness of the bottom cover partially, thereby reducing the manufacturing cost of the bottom cover. Furthermore, this design allows the compression band to be connected to an external plug connection port at the edge of the watch. This reduces the volume of the compression band stacked under the watch, facilitating a lightweight and thin design of the wearable device.

The elastic modulus of the main body member may be the same as or different from the elastic modulus of the first cover member.

In one implementation example, the air nozzle of the blood pressure measurement assembly is plugged into the internal plug connection port, and the elastic coefficient of the air nozzle of the blood pressure measurement assembly is greater than the elastic coefficient of the first cover member. That is, the air nozzle of the blood pressure measurement assembly is made of a hard material, and the first cover member is made of an elastic material. Specifically, the air nozzle of the blood pressure measurement assembly is made of a relatively hard material, and the first cover member is made of a relatively soft material. When the air nozzle of the blood pressure measurement assembly is inserted into the internal plug connection port, the first cover member is deformed when pressed by the air nozzle of the blood pressure measurement assembly to fit snugly against the air nozzle of the blood pressure measurement assembly, ensuring airtightness between the air nozzle of the blood pressure measurement assembly and the first cover member.

The first cover member is made of an elastic material such as silica gel or TPU (thermoplastic polyurethanes).

In one implementation, the bottom cover further includes a second cover member, the second cover member being fixed to the side of the main body member away from the first cover member, the second cover member forming an external plug connection port, the air nozzle of the compression band being plugged into the external plug connection port, and the elastic coefficient of the air nozzle of the compression band being greater than the elastic coefficient of the second cover member. That is, the air nozzle of the compression band is made of a hard material, and the second cover member is made of an elastic material. Specifically, the air nozzle of the compression band is made of a relatively hard material, and the second cover member is made of a relatively soft material. When the air nozzle of the compression band is inserted into the external plug connection port, the second cover member is deformed and tightly fits the air nozzle of the compression band when pressed by the air nozzle of the compression band, ensuring airtightness between the air nozzle of the compression band and the second cover member.

The second cover member is made of an elastic material such as silica gel or TPU.

In one implementation, the main body member includes a bottom surface that is spaced from the watch face cavity, the bottom surface of the main body member is partially recessed to form an assembly groove, a groove wall of the assembly groove is partially protruding to form an external plug connection nozzle, an external plug connection port is formed inside the external plug connection nozzle, an air nozzle of the compression band is located in the assembly groove, and the external plug connection nozzle is plugged into the air nozzle of the compression band, i.e., the air nozzle of the compression band is sleeved to the external plug connection nozzle, and a connection between the compression band and the main body member is realized.

Furthermore, the elastic modulus of the main body member is greater than that of the air nozzle of the compression band. That is, the main body member is made of a hard material, and the air nozzle of the compression band is made of an elastic material. Specifically, the main body member is made of a relatively hard material, and the air nozzle of the compression band is made of a relatively soft material. When the external plug connection nozzle is inserted into the air nozzle of the compression band, since the external plug connection nozzle is relatively hard and the air nozzle of the compression band is relatively soft, when the air nozzle of the compression band is pushed in by the external plug connection nozzle, it deforms and fits snugly against the external plug connection nozzle, ensuring airtightness between the external plug connection nozzle and the air nozzle of the compression band.

In one implementation example, the opening of the assembly groove is located on the bottom surface of the main body member, the assembly groove is recessed in a direction from the bottom surface to the top surface of the main body member and passes through the peripheral surface of the main body member, and the air nozzle of the compression band is located in the assembly groove. In this case, the compression band shares some or all of the thickness distance of the main body member in the Z direction. This reduces the effect of the presence of the compression band on the thickness of the wearable device.

In one implementation, the bottom cover further includes a fixing member that is fixed to the side of the compression band that is away from the main body member and is in contact with the compression band. This not only prevents the air nozzle of the compression band from coming off the external plug connection nozzle, thereby maintaining the plug connection stability between the air nozzle of the compression band and the external plug connection nozzle, but also prevents the compression band from coming off the assembly groove, thereby improving the connection stability between the compression band and the main body member.

In one implementation example, the external plug connection nozzle is located between the top surface of the main body member and the bottom surface of the main body member, i.e., the external plug connection nozzle shares the entire thickness distance of the main body member in the Z direction. This reduces the effect of the presence of the external plug connection nozzle on the thickness of the bottom cover, facilitating the realization of a lightweight and thin design for the wearable device.

In one implementation example, the peripheral surface of the main body member partially protrudes to form an external plug connection nozzle, an external plug connection port is formed inside the external plug connection nozzle, and the air nozzle of the compression band is connected to the external plug connection nozzle by a sleeve, i.e., the external plug connection nozzle is plugged into the air nozzle of the compression band. In this case, the compression band does not occupy the bottom space of the bottom cover, but only shares some or all of the thickness distance in the Z direction of the main body member, which reduces the impact of the presence of the compression band on the thickness of the wearable device, making it easier to design a lightweight and thin wearable device.

Furthermore, the elastic modulus of the air nozzle of the compression band is smaller than that of the main body member. That is, the air nozzle of the compression band is made of an elastic material, and the main body member is made of a hard material. Specifically, the air nozzle of the compression band is made of a relatively soft material, and the main body member is made of a relatively hard material. When the external plug connection nozzle is inserted into the air nozzle of the compression band, since the external plug connection nozzle is relatively hard and the air nozzle of the compression band is relatively soft, when the air nozzle of the compression band is pushed in by the external plug connection nozzle, it deforms and fits snugly against the external plug connection nozzle, ensuring airtightness between the external plug connection nozzle and the air nozzle of the compression band.

In one implementation example, the wearable device further includes an air sensor located in the flow path and fixed to the inner wall of the flow path. This allows the air components present in the environment surrounding the wearable device to be analyzed when the wearable device performs blood pressure measurements, thereby improving the functional diversity of the wearable device and improving the user's usage experience.

In one implementation, there are two external plug connection ports, two flow paths, and two internal plug connection ports, the two external plug connection ports being a first external plug connection port and a second external plug connection port, the two flow paths being a first flow path and a second flow path, the two internal plug connection ports being a first internal plug connection port and a second internal plug connection port, the first external plug connection port, the first flow path, and the first internal plug connection port being in continuous communication, and the second external plug connection port, the second flow path, and the second internal plug connection port being in continuous communication. The blood pressure measurement assembly includes an air pump and a pressure sensor, an air nozzle of the air pump in communication with the first internal plug connection port, and an air nozzle of the pressure sensor in communication with the second internal plug connection port. The compression band includes two air nozzles, one of which is connected to a first external plug connection port, so that the air pump sends the sucked air to the air bag of the compression band through a first flow path, or the air in the air bag of the compression band enters the air pump through the first flow path and is discharged from the air pump, and the other air nozzle is connected to a second external plug connection port, so that the air in the air bag of the compression band is sent to a pressure sensor through a second flow path, and the pressure sensor detects the pressure change in the air bag, thereby measuring blood pressure.

In this implementation, the pressure sensor and the air nozzle of the air pump each communicate with the air nozzle of the compression band through two flow paths rather than sharing one flow path. This not only improves the mounting flexibility of the blood pressure measurement assembly in the cavity of the watch face, but also prevents air transmission between the pressure sensor and the air bag of the compression band, and between the air pump and the air bag of the compression band from interfering with each other, thereby promoting improvement of the measurement sensitivity and measurement accuracy of the blood pressure measurement assembly in the blood pressure measurement process.

In one implementation, the bezel or bottom cover includes a vent hole that communicates with a cavity within the watch face and with the outside of the watch face. In this way, the air pump draws air from the surrounding environment through the vent hole during the blood pressure measurement process to fill the air bladder with air for blood pressure measurement.

In one implementation, the wearable device further includes a heart rate detection sensor, and the bottom cover has a central mounting hole spaced apart from the internal plug connection port, and the heart rate detection sensor is housed in a cavity within the watch face and either directly faces the mounting hole or is at least partially housed within the mounting hole. This increases the functional versatility of the wearable device and improves the user's usage experience by sending a detection signal through the mounting hole to measure the user's heart rate.

The following describes the embodiments of the present application with reference to the accompanying drawings.

Figure 1 is a schematic structural diagram of a wearable device 1000 according to one embodiment of the present application. Figure 2 is a schematic exploded structural diagram of the wearable device 1000 shown in Figure 1.

The wearable device 1000 may be a wrist-type electronic product such as a watch, a smart watch, a wristband, or a smart band. The wearable device 1000 in the embodiment shown in FIG. 1 and FIG. 2 is described using a smart watch as an example. For ease of description, as shown in FIG. 1, the width direction of the wearable device 1000 is the X direction, the length direction of the wearable device 1000 is the Y direction, and the thickness direction of the wearable device 1000 is the Z direction. Any two of the X direction, the Y direction, and the Z direction are perpendicular to each other.

The wearable device 1000 includes a watch face 100, a watch band 200, and a compression band 300. The watch face 100 includes a bezel 10, and the watch band 200 is connected to the bezel 10. There are two watch bands 200. The two watch bands 200 are a first watch band 200 and a second watch band 200. The first watch band 200 and the second watch band 200 are respectively connected to two opposing sides of the bezel 10. The first watch band 200 is provided with a first locking portion (not shown), and the second watch band 200 is provided with a second locking portion (not shown). The first locking portion and the second locking portion are removably locked to each other, allowing the wearable device 1000 to be worn on the user's wrist. It should be understood that the mating structure between the first locking portion and the second locking portion may be a watch buckle structure, such as a hook buckle, a hidden clasp, a push button hidden clasp, a leather deployment buckle, a secure fold-over clasp, a fold-over clasp, or a buckle, although this is not particularly limited in this application.

The compression band 300 and the watch band 200 are stacked. Specifically, the compression band 300 is stacked with the first watch band 200 and is located under the watch band 200. When the user wears the wearable device 1000, the compression band 300 is located on the side of the watch band 200 and on the user's wrist, and is in close contact with the wrist artery of the user's wrist. Please note that the directional terms such as "top" and "bottom" used for the wearable device 1000 illustrated in the embodiment are mainly described based on the presented directions in Figures 1 and 2, and do not limit the direction of the wearable device 1000 in an actual application scenario.

Figure 3 is a schematic structural diagram of the watch face 100 in the wearable device 1000 shown in Figure 2. Figure 4 is a schematic exploded structural diagram of the watch face 100 shown in Figure 3.

In this embodiment, the watch face 100 is a rectangular parallelepiped structure. The watch face 100 further includes a top cover 20, a bottom cover 30, a processor (not shown), a blood pressure measurement assembly 40, and a sensor assembly (not shown). The bottom cover 30 and the top cover 20 are located on two opposite sides of the bezel 10. The processor, the blood pressure measurement assembly 40, and the sensor assembly are located between the top cover 20 and the bottom cover 30. The X direction of the wearable device 1000 is the width direction of the watch face 100, the Y direction of the wearable device 1000 is the length direction of the watch face 100, and the Z direction of the wearable device 1000 is the thickness direction of the watch face 100, that is, the direction from the bottom cover 30 to the top cover 20 of the watch face 100. The above-mentioned rectangular parallelepiped structure includes a rectangular parallelepiped structure and a structure similar to a rectangular parallelepiped. By a structure resembling a rectangular parallelepiped, it is meant that the outer surface of the rectangular parallelepiped may be partially concave or partially protruding. The following description of the structure shape can be understood in a similar manner. It should be understood that in other embodiments, the watch face 100 may alternatively be cylindrical, conical, cubic, or another geometric shape.

Figure 5 is a schematic structural diagram of the bezel 10 on the watch face 100 shown in Figure 4. Figure 6 is a schematic structural diagram of the bezel 10 shown in Figure 5 cut in the A-A direction. Please note that in the accompanying drawings of this application, "cut in the A-A direction" means cutting along the plane where the A-A line and the arrows at both ends of the A-A line are located. The following explanation of the accompanying drawings should be understood in the same way.

The bezel 10 is a substantially rectangular frame structure. The bezel 10 includes a top surface 101 and a bottom surface 102 disposed opposite each other, and a peripheral surface 103 connected between the top surface 101 and the bottom surface 102. The bottom surface 102 of the bezel 10 is partially recessed to form a first fixing groove 104. That is, the opening of the first fixing groove 104 is located on the bottom surface 102 of the bezel 10, and the first fixing groove 104 is recessed in the direction from the bottom surface 102 to the top surface 101 of the bezel 10.

The peripheral surface 103 includes a first peripheral surface 105 and a second peripheral surface 106 that are arranged opposite each other, and a third peripheral surface 107 and a fourth peripheral surface 108 that are connected between the first peripheral surface 105 and the second peripheral surface 106. The third peripheral surface 107 and the fourth peripheral surface 108 are arranged opposite each other. The first peripheral surface 105 partially protrudes to form a first fixing lug 11, which protrudes from the first peripheral surface 105 in a direction away from the second peripheral surface 106. There are two first fixing lugs 11, and the two first fixing lugs 11 are arranged at two ends of the first peripheral surface 105 at intervals in the X-axis direction. Furthermore, the second peripheral surface 106 partially protrudes to form a second fixing lug (not shown), which protrudes from the second peripheral surface 106 in a direction away from the first peripheral surface 105. There are two second fixed lugs, and the two second fixed lugs are spaced apart in the X-axis direction at two ends of the second peripheral surface 106. When connecting the watch band 200 to the bezel 10, the first watch band 200 is removably attached between the two first fixed lugs 11, and the second watch band 200 is removably attached between the two second fixed lugs.

The bezel 10 is provided with a ventilation hole 109. Specifically, the third peripheral surface 107 is partially recessed to form the ventilation hole 109. Specifically, the opening of the ventilation hole 109 is located on the third peripheral surface 107, and the ventilation hole 109 extends in a direction from the third peripheral surface 107 to the fourth peripheral surface 108, so that the outside of the bezel 10 communicates with the inside of the bezel 10, and a pressure balance between the inside of the bezel 10 and the outside of the bezel 10 is ensured. In order to prevent moisture on the outside of the bezel 10 from entering the inside of the bezel 10 through the ventilation hole 109, a waterproof breathable film is disposed on the ventilation hole 109, and the components located inside the bezel 10 can be protected.

Referring to FIG. 4, the top cover 20 is a substantially rectangular plate-like structure that is located on the side of the bezel 10 closer to the top surface 101 and fits over the bezel 10. In this embodiment, the top cover 20 is a display. The display includes a display surface 201 that is remote from the bezel 10 and is configured to display information such as the time, an icon, or a physiological parameter of the user.

In one implementation, the display includes a cover plate and a display panel secured to the cover plate. The cover plate may be made of a transparent material such as glass. The display panel may be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, or an active-matrix organic light-emitting diode (AMOLED) display, a flex light-emitting diode (FLED) display, a mini LED, a micro LED, a micro OLED, a quantum dot light emitting diode (QLED), or the like. The display panel may further incorporate a touch control function. Specifically, the display panel is a touch-controlled display panel, i.e., the display panel may be used not only as an input device for receiving input, but also as a device for providing output. The display panel is electrically connected to the processor. The display panel may generate touch control signals and transmit the touch control signals to the processor. The processor receives the touch control signals and controls to activate application (app) software on the watch face 100 based on the touch control signals. For example, a user may select a graph to open or edit by touching or pressing the position of the graph on the display.

Figure 7 is a schematic structural diagram of the watch face 100 shown in Figure 3 cut in the B-B direction.

The top cover 20 is fixed to the side of the bezel 10 that is closer to the top surface 101. Specifically, the top cover 20 is fixed to the top surface 101 of the bezel 10. The edge of the top cover 20 may be attached to the top surface 101 of the bezel 10 with an adhesive. It should be understood that the top cover 20 is not limited to the 2D (Dimension) display shown in FIG. 7, but may alternatively be a 2.5D curved screen or a 3D curved screen.

The bottom cover 30 is fixed to the side of the bezel 10 that is away from the top cover 20, i.e., the bottom cover 30 is fixed to the side of the bezel 10 that is closer to the bottom surface 102. Specifically, the peripheral edge of the bottom cover 30 is connected to the bezel 10 and together with the bezel 10 encloses the watch face cavity 110. The bottom cover 30 and the top cover 20 are fixed to two opposite sides of the bezel 10, respectively. When the user wears the wearable device 1000, the top cover 20 is positioned away from the user's wrist and the bottom cover 30 is positioned close to the user's wrist. Please note that the watch face cavity 110 is inside the bezel 10 and the outside of the watch face 100 is outside the bezel 10.

In this embodiment, the peripheral edge of the bottom cover 30 is removably attached to the first fixing groove 104. This facilitates the maintenance and replacement of functional components inside the watch face 100, such as memory cards, SIM cards, and speakers. In this case, the bezel 10 may be made of a metal alloy material, such as a titanium alloy or an aluminum magnesium alloy. The bottom cover 30 may be made of engineering plastics, such as PC (polycarbonate) or ABS (acrylonitrile butadiene styrene copolymer), or a metal alloy, such as a titanium alloy or an aluminum magnesium alloy. Of course, in order to improve the structural stability of the watch face 100, the bottom cover 30 and the bezel 10 may be integrally formed, and the bottom cover 30 and the bezel 10 may form an integral structure by assembly. In this case, the bezel 10 and bottom cover 30 may be made using a metal material.

Please refer to Figures 7 and 8. Figure 8 is a schematic structural diagram of the bottom cover 30 of the watch face 100 shown in Figure 4.

The bottom cover 30 includes a top surface 301 facing the watch face cavity 110, a bottom surface 302 disposed opposite the top surface 301, and a peripheral surface 303 connected between the top surface 301 and the bottom surface 302. The top surface 301 of the bottom cover 30 is parallel to the X-Y plane. It should be understood that the peripheral edge of the bottom cover 30 refers to a part of the bottom cover 30 formed by the enclosing of the edge of the bottom cover 30, i.e., the top surface 301 of the bottom cover 30, the edge of the peripheral surface 303 of the bottom cover 30, and the edge of the bottom surface 302 of the bottom cover 30. The peripheral edge of the bottom surface 302 is connected to the bezel 10, i.e., the edge of the top surface 301 of the bottom cover 30, the peripheral edge of the bottom cover 30, or the edge of the bottom surface 302 of the bottom cover 30 is connected to the bezel 10.

A mounting hole 304 is provided in the center of the bottom cover 30. Specifically, the top surface 301 of the bottom cover 30 is partially recessed to form the mounting hole 304. Specifically, the opening of the mounting hole 304 is located on the top surface 301 of the bottom cover 30, and the mounting hole 304 extends in a direction from the top surface 301 to the bottom surface 302 of the bottom cover 30, passing through the bottom surface of the bottom cover 30.

Figure 9 is a schematic structural diagram of the bottom cover 30 shown in Figure 8 cut in the C-C direction. Figure 10 is a schematic structural diagram of a partial front view of the structure shown in Figure 9.

The bottom cover 30 is provided with an external plug connection port 305, a flow path 306, and an internal plug connection port 307 that are continuously connected. In this embodiment, there are two external plug connection ports 305, two flow paths 306, and two internal plug connection ports 307. For ease of distinction, the two external plug connection ports 305 are named the first external plug connection port 305 and the second external plug connection port 305, the two flow paths 306 are named the first flow path 306 and the second flow path 306, and the two internal plug connection ports 307 are named the first internal plug connection port 307 and the second internal plug connection port 307. The first external plug connection port 305, the first flow path 306, and the first internal plug connection port 307 are continuously connected, and the second external plug connection port 305, the second flow path 306, and the second internal plug connection port 307 are continuously connected.

For ease of understanding, the following uses the first external plug connection port 305, the first flow path 306, and the first internal plug connection port 307 as an example of description. In the following description, the external plug connection port 305 refers to the first external plug connection port 305, the flow path 306 refers to the first flow path 306, and the internal plug connection port 307 refers to the first internal plug connection port 307. It should be understood that the structures of the second external plug connection port 305 and the first external plug connection port 305 are substantially the same, the structures of the second flow path 306 and the first flow path 306 are substantially the same, and the structures of the second internal plug connection port 307 and the first internal plug connection port 307 are substantially the same, so the details will not be repeated.

Specifically, the external plug connection port 305 is located at an edge position of the bottom cover 30. The external plug connection port 305 extends in the Z direction, i.e., the external plug connection port 305 extends in the thickness direction of the bottom cover 30. That is, the extension direction of the external plug connection port 305 is perpendicular to the XY plane. In other words, the extension direction of the external plug connection port 305 is perpendicular to the upper surface 301 of the bottom cover 30. The external plug connection port 305 has a substantially cylindrical hollow structure, and the external plug connection port 305 has a central axis O1. It should be understood that the external plug connection port 305 may alternatively have a rectangular hollow structure or a hollow structure of another shape.

In the following, in order to facilitate understanding of the structure of the bottom cover 30, the surface on which the top surface 301 of the bottom cover 30 is located is defined as the origin position in the Z direction, the direction above the top surface 301 of the bottom cover 30 is the [Z+] direction, and the direction below the top surface 301 of the bottom cover 30 is the [Z-] direction. The top surface 301 of the bottom cover 30 is the reference surface for machining or assembling the bottom cover 30, that is, the top surface 301 of the bottom cover 30 is the positioning reference for machining or assembling the bottom cover 30. This determines the specific position of each part or component on the watch face 100. Please note that the directional terms such as "upper" and "lower" used for the bottom cover 30 exemplified in this embodiment are mainly described based on the presentation direction in Figures 9 and 10, and do not limit the direction of the bottom cover 30 in an actual application scenario.

The distance between the external plug connection port 305 and the top surface 301 of the bottom cover 30 forms a first distance range [Z11, Z12]. The distance between one end of the external plug connection port 305 and the top surface 301 of the bottom cover 30 forms the starting point Z11 of the first distance range, and the distance between the other end of the external plug connection port 305 and the top surface 301 of the bottom cover 30 forms the ending point Z12 of the first distance range.

Specifically, the external plug connection port 305 includes a lower port and an upper port arranged opposite each other, and the lower port and the upper port of the external plug connection port 305 are respectively located on two sides of the upper surface 301 of the bottom cover 30. The lower port of the external plug connection port 305 is located below the upper surface 301 of the bottom cover 30 and communicates with the outside of the bottom cover 30. The distance between the lower port of the external plug connection port 305 and the upper surface 301 of the bottom cover 30 is Z11, that is, Z11 is equal to the Z coordinate value of the upper surface 301 of the bottom cover 30 minus the Z coordinate value of the lower port of the external plug connection port 305, and Z11 is less than 0. The upper port of the external plug connection port 305 is located above the upper surface 301 of the bottom cover 30 and communicates with the flow path 306. The distance between the upper port of the external plug connection port 305 and the upper surface 301 of the bottom cover 30 is Z12, i.e., Z12 is equal to the Z coordinate value of the upper port of the external plug connection port 305 minus the Z coordinate value of the upper surface 301 of the bottom cover 30, and Z12 is greater than 0.

The internal plug connection port 307 and the external plug connection port 305 are spaced apart. In this embodiment, the internal plug connection port 307 is located at a central position of the bottom cover 30 and is spaced apart from the mounting hole 304. When the bottom cover 30 is connected to the bezel 10, the internal plug connection port 307 is farther from the bezel 10 than the external plug connection port 305, i.e., the external plug connection port 305 is closer to the bezel 10 than the internal plug connection port 307.

Specifically, the internal plug connection port 307 and the external plug connection port 305 have the same extension direction, both extending in the Z direction. That is, the internal plug connection port 307 also extends in the thickness direction of the bottom cover, in other words, the extension direction of the internal plug connection port 307 is also perpendicular to the upper surface 301 of the bottom cover 30, that is, the extension direction of the internal plug connection port 307 is also perpendicular to the XY plane. The internal plug connection port 307 has a substantially cylindrical hollow structure, and the internal plug connection port 307 has a central axis O2. It should be understood that the internal plug connection port 307 may alternatively have a rectangular hollow structure or a hollow structure of another shape.

The distance between the internal plug connection port 307 and the top surface 301 of the bottom cover 30 forms a second distance range [Z21, Z22]. The distance between one end of the internal plug connection port 307 and the top surface 301 of the bottom cover 30 forms the start point Z21 of the second distance range, and the distance between the other end of the internal plug connection port 307 and the top surface 301 of the bottom cover 30 forms the end point Z22 of the second distance range.

Specifically, the internal plug connection port 307 includes a lower port and an upper port arranged opposite each other, and the lower port and the upper port of the internal plug connection port 307 are respectively located on two sides of the upper surface 301 of the bottom cover 30. The lower port of the internal plug connection port 307 is located below the upper surface 301 of the bottom cover 30 and communicates with the inside of the bottom cover 30. The distance between the lower port of the internal plug connection port 307 and the upper surface 301 of the bottom cover 30 is Z21, that is, Z21 is equal to the Z coordinate value of the upper surface 301 of the bottom cover 30 minus the Z coordinate value of the lower port of the internal plug connection port 307, and Z21 is less than 0. The upper port of the internal plug connection port 307 is located above the upper surface 301 of the bottom cover 30 and communicates with the flow path 306. The distance between the upper port of the internal plug connection port 307 and the upper surface 301 of the bottom cover 30 is Z22, i.e., Z22 is equal to the Z coordinate value of the upper port of the internal plug connection port 307 minus the Z coordinate value of the upper surface 301 of the bottom cover 30, and Z22 is greater than 0.

In this embodiment, the second distance range [Z21, Z22] partially overlaps with the first distance range [Z11, Z12]. That is, the external plug connection port 305 and the internal plug connection port 307 are partially stacked in the direction from the central axis O1 of the external plug connection port 305 to the central axis O2 of the internal plug connection port 307. In other words, the external plug connection port 305 and the internal plug connection port 307 share a part of the thickness distance in the Z direction of the bottom cover 30. In this case, the external plug connection port 305 and the internal plug connection port 307 are relatively close to each other in the Z direction. This can reduce the thickness distance of the bottom cover 30 occupied in the Z direction by the external plug connection port 305 and the internal plug connection port 307, which promotes the reduction of the thickness in the Z direction of the bottom cover 30 and promotes the realization of a lightweight and thin design of the watch face 100.

It should be understood that in another embodiment, the second distance range [Z21, Z22] may alternatively completely overlap with the first distance range [Z11, Z12]. In this case, the lower port of the external plug connection port 305 may be flush with the lower port of the internal plug connection port 307, and the external plug connection port 305 and the internal plug connection port 307 are fully stacked in the direction from the central axis O1 of the external plug connection port 305 to the central axis O2 of the internal plug connection port 307. In other words, the external plug connection port 305 and the internal plug connection port 307 share the entire thickness distance of the bottom cover 30 in the Z direction, i.e., the external plug connection port 305 is completely flush with the internal plug connection port 307 in the Z direction. This minimizes the thickness distance of the bottom cover 30 occupied in the Z direction by the external plug connection port 305 and the internal plug connection port 307, thereby facilitating the realization of a lightweight and thin design of the watch face 100.

The flow path 306 communicates between the external plug connection port 305 and the plug connection port 307. Here, the flow path 306 is Z-shaped. It should be understood that in other embodiments, the flow path 306 may be hyphen-shaped, S-shaped, L-shaped, etc.

A third distance range [Z31, Z32] is formed between the flow path 306 and the upper surface 301 of the bottom cover 30. Specifically, the flow path 306 includes a lower end surface and an upper end surface that are arranged opposite each other, and the lower end surface and the upper end surface of the flow path 306 are located on two sides of the upper surface 301 of the bottom cover 30, respectively. The lower end surface of the flow path 306 is located below the upper surface 301 of the bottom cover 30. The distance between the lower end surface of the flow path 306 and the upper surface 301 of the bottom cover 30 is Z31, that is, Z31 is equal to the Z coordinate value of the upper surface 301 of the bottom cover 30 minus the Z coordinate value of the lower end surface of the flow path 306, and Z31 is less than 0. The upper end surface of the flow path 306 is located above the upper surface 301 of the bottom cover 30. The distance between the upper end surface of the flow path 306 and the upper surface 301 of the bottom cover 30 is Z32, i.e., Z32 is equal to the Z coordinate value of the upper end surface of the flow path 306 minus the Z coordinate value of the upper surface 301 of the bottom cover 30, and Z32 is greater than 0.

In this embodiment, the third distance range [Z31, Z32] is a combination set of the second distance range [Z21, Z22] and the first distance range [Z11, Z12], that is, the distance between any position of the flow path 306 and the upper surface 301 of the bottom cover 30 is always included in the first distance range [Z11, Z12] or the second distance range [Z21, Z22]. That is, in the direction from the central axis O1 of the external plug connection port 305 to the central axis O2 of the internal plug connection port 307, one part of the flow path 306 is stacked with the internal plug connection port 307, and the other part of the flow path 306 is stacked with the external plug connection port 305. In other words, the flow path 306 shares the entire thickness distance in the Z direction of the bottom cover 30 with the internal plug connection port 307 and the external plug connection port 305. This prevents the bottom cover 30 from taking up any additional thickness distance in the Z direction caused by the presence of the flow path 306, which helps reduce the thickness of the bottom cover 30 in the Z direction and achieve a lightweight, thin design for the watch face 100.

In one implementation, the flow path 306 includes a first flow path 3061, a second flow path 3062, and a third flow path 3063 that are continuously connected to each other. The first flow path 3061 extends along the XY plane and is connected to the upper port of the external plug connection port 305. The second flow path 3062 extends in the Z direction and is connected between the first flow path 3061 and the third flow path 3063. The third flow path 3063 extends along the XY plane and is connected to the lower port of the internal plug connection port 307. Specifically, the cross-sectional area of the flow path 306 is greater than 1 ^mm2 , which suppresses air resistance generated when air flows inside the flow path 306, thereby ensuring air flow between the external plug connection port 305 and the internal plug connection port 307. The cross-sectional shape of the flow path 306 includes, but is not limited to, a circle, a square, or another geometric shape.

Figure 11 is a schematic exploded structural diagram of the bottom cover 30 shown in Figure 8. Figure 12 is a schematic structural diagram of the main body member 31 in the bottom cover 30 shown in Figure 11.

In this embodiment, the bottom cover 30 includes a main body member 31, a first cover member 32, and a fixing member 33. The first cover member 32 and the fixing member 33 are located on two opposite sides of the main body member 31. The main body member 31 includes an upper surface 311 and a bottom surface 312 arranged opposite each other, and a peripheral surface 313 connected between the upper surface 311 and the bottom surface 312. The main body member is made of a plastic material such as polycarbonate (PC) or a metal material such as stainless steel. It should be understood that the upper surface 311 of the main body member 31 is the upper surface 301 of the bottom cover 30 described above, and the peripheral surface 313 of the main body member 31 is the peripheral surface 303 of the bottom cover 30 described above.

The upper surface 311 of the main body member 31 partially protrudes to form a boss 314. In this embodiment, there are two bosses 314, and the two bosses 314 are spaced apart. For ease of distinction, the two bosses 314 are named a first boss 314 and a second boss 314. In the following, the structure of the main body member 31 will be described in detail by using the first boss 314 as an example. It should be understood that the boss 314 mentioned below refers to the first boss 314. The structures of the second boss 314 and the first boss 314 are substantially the same, so the details will not be repeated below.

Figure 13 is a schematic structural diagram of the main body member 31 shown in Figure 12, cut in the D-D direction.

The boss 314 includes an upper surface 315 having the same orientation as the upper surface 311 of the main body member 31, and the upper surface 315 of the boss 314 is partially recessed to form a first mounting groove 316 and a flow groove 317. Specifically, the opening of the first mounting groove 316 is located at a central position of the upper surface 315 of the boss 314. The first mounting groove 316 is recessed in a direction from the upper surface 315 of the boss 314 to the upper surface 311 of the main body member 31. The first mounting groove 316 is substantially L-shaped. The first mounting groove 316 includes a first groove body 3161 and a second groove body 3162. The first groove body 3161 extends along the XY plane. The bottom groove wall of the first groove body 3161 is partially recessed to form a second groove body 3162, i.e., the opening of the second groove body 3162 is located at the bottom groove wall of the first groove body 3161. The second groove body 3162 extends in a direction from the bottom groove wall of the first groove body 3161 to the bottom surface 312 of the main body member 31, i.e., the second groove body 3162 extends in the Z direction.

The groove wall of the first mounting groove 316 is partially recessed to form the flow groove 317, i.e., the opening of the flow groove 317 is located in the groove wall of the first mounting groove 316. Specifically, the flow groove 317 is Z-shaped. The flow groove 317 includes a first portion 3171, a second portion 3172, and a third portion 3173 that are continuously connected. The openings of both the first portion 3171 and the second portion 3172 are located in the bottom groove wall of the first groove body 3161. Both the first portion 3171 and the second portion 3172 are recessed in a direction from the bottom groove wall of the first groove body 3161 to the bottom surface 312 of the main body member 31. The first portion 3171 extends along the XY plane, and the second portion 3172 extends in the Z direction and passes through the groove side wall of the second groove 3162. The bottom groove wall of the second groove body 3162 is recessed in the Z direction to form the third portion 3173, i.e., the third portion 3173 is located below the second groove body 3162. The third portion 3173 extends along the XY plane.

Please refer to Figures 13 and 14. Figure 14 is a schematic structural diagram of the main body member 31 shown in Figure 12 from another perspective.

The bottom surface 312 of the main body member 31 partially protrudes to form a circular boss 312a. Specifically, the circular boss 312a is connected to a central region of the bottom surface 312 of the main body member 31. The circular boss 312a protrudes from the bottom surface 312 of the main body member 31 in a direction away from the top surface 311. The circular boss 312a includes a bottom surface 312b having the same orientation as the bottom surface 312 of the main body member 31. The mounting hole 304 passes through the bottom surface 312b of the circular boss 312a. When the wearable device 1000 is worn by a user, the bottom surface 312b of the circular boss 312a can be in close contact with the user's wrist.

The bottom surface 312 of the main body member 31 is partially recessed to form a second fixing groove 318 and an assembly groove 319. Specifically, the opening of the second fixing groove 318 is located in the edge region of the bottom surface 312 of the main body member 31. The second fixing groove 318 is recessed in a direction from the bottom surface 312 to the top surface 311 of the main body member 31 and passes through the peripheral surface 313 of the main body member 31. The bottom groove wall of the second fixing groove 318 is partially recessed to form an assembly groove 319. The assembly groove 319 is recessed in a direction from the bottom groove wall of the second fixing groove 318 to the top surface 311 of the main body member 31 and passes through the peripheral surface 313 of the main body member 31.

The groove wall of the assembly groove 319 partially protrudes to form the external plug connection nozzle 310, and the external plug connection port 305 is formed inside the external plug connection nozzle 310, and the external plug connection port 305 communicates with the first portion 3171 of the flow groove 317. In this embodiment, the external plug connection nozzle 310 is provided on the bottom groove wall of the assembly groove 319, i.e., the bottom groove wall of the assembly groove 319 partially protrudes to form the external plug connection nozzle 310. Of course, in another embodiment, the external plug connection nozzle 310 may alternatively be disposed on the groove side wall of the assembly groove 319, i.e., the groove side wall of the assembly groove 319 partially protrudes to form the external plug connection nozzle 310. It should be understood that the shape of the external plug connection nozzle 310 is not limited to the circular tubular structure shown in FIG. 14, but may alternatively be a square tubular structure or a tubular structure of another geometric shape.

In this embodiment, there are two external plug connection nozzles 310. The two external plug connection nozzles 310 are a first external plug connection nozzle 310 and a second external plug connection nozzle 310, and the first external plug connection nozzle 310 and the second external plug connection nozzle 310 are arranged at an interval. The first external plug connection port 305 is formed inside the first external plug connection nozzle 310, and the first external plug connection port 305 is in communication with the first portion 3171 of the flow groove 317 in the first boss 314. The second external plug connection port 305 is formed inside the second external plug connection nozzle 310, and the second external plug connection port 305 is in communication with the first portion 3171 of the flow groove 317 in the second boss 314. For ease of understanding, the first external plug connection nozzle 310 is used as an example of the description below. Unless otherwise specified, the external plug connection nozzle 310 referred to below refers to the first external plug connection nozzle 310. Please note that the structures of the second external plug connection nozzle 310 and the first external plug connection nozzle 310 are basically the same, so the details will not be repeated below.

Specifically, the bottom groove wall of the assembly groove 319 is partially recessed to form the avoidance groove 3191. That is, the opening of the avoidance groove 3191 is located in the bottom groove wall of the assembly groove 319. It can be understood that the shape of the avoidance groove 3191 is not limited to the circular hollow structure shown in FIG. 14, but may alternatively be a rectangular or strip-shaped hollow structure.

The avoidance groove 3191 is recessed in the direction from the bottom groove wall of the assembly groove 319 to the top surface 311 of the main body member 31. The bottom groove wall of the avoidance groove 3191 partially protrudes to form the external plug connection nozzle 310, that is, the external plug connection nozzle 310 extends in the direction from the bottom groove wall of the avoidance groove 3191 to the bottom groove wall of the assembly groove 319. Specifically, the external plug connection nozzle 310 is located between the top surface 311 and the bottom surface 312 of the main body member 31, that is, the external plug connection nozzle 310 shares the entire thickness distance of the main body member 31 in the Z direction. This suppresses the effect of the presence of the external plug connection nozzle 310 on the thickness of the bottom cover 30, which promotes the realization of a lightweight and thin design of the watch face 100.

In this embodiment, the second distance range [Z21, Z22] only partially overlaps with the first distance range [Z11, Z12], so the lower port of the external plug connection port 305 is not flush with the lower port of the internal plug connection port 307. In this case, the external plug connection nozzle 310 protrudes from the bottom groove wall of the assembly groove 319, but does not extend beyond the bottom surface 312 of the main body member 31, nor does it extend beyond the bottom surface 312b of the circular boss 312a. Compared to an embodiment in which the second distance range [Z21, Z22] completely overlaps with the first distance range [Z11, Z12], in the wearable device 1000 illustrated in this embodiment, the length of the external plug connection nozzle 310 in the Z direction is longer, and the area of the outer circumferential surface of the external plug connection nozzle 310 is also larger.

Furthermore, the bottom groove wall of the assembly groove 319 is partially recessed to form a first fixing hole 3192. Specifically, the opening of the first fixing hole 3192 is located in an edge region of the bottom groove wall of the assembly groove 319 and is spaced apart from the opening of the avoidance groove 3191. The first fixing hole 3192 is recessed in a direction from the bottom groove wall of the assembly groove 319 towards the top surface 311 of the main body member 31. There are two first fixing holes 3192, the two first fixing holes 3192 are spaced apart and are located on two opposite sides of the avoidance groove 3191.

Referring to FIG. 11, the first cover member 32 is located on the side of the main body member 31 close to the top surface 311, and the first cover member 32 forms an internal plug connection port 307. In this embodiment, there are two first cover members 32, and the two first cover members 32 are located on the same side of the main body member 31. Specifically, one first cover member 32 forms the first internal plug connection port 307 and fits into the first boss 314. The other first cover member 32 forms the second internal plug connection port 307 and fits into the second boss 314. The structures of the two first cover members 32 are basically the same.

Figure 15 is a schematic structural diagram of the first cover member 32 shown in Figure 11.

The first cover member 32 includes a first cover part 321 and a first plug connection part 322 connected to the first cover part 321. In this embodiment, the first cover part 321 has a substantially flat plate-like structure. The first cover part 321 includes an upper surface 323 and a bottom surface 324 arranged opposite each other. The first plug connection part 322 is connected to the bottom surface 324 of the first cover part 321. The first plug connection part 322 extends from the bottom surface 324 of the first cover part 321 in a direction away from the upper surface 323 and has a substantially circular tubular structure. The first plug connection part 322 includes a bottom surface 325 having the same orientation as the bottom surface 324 of the first cover part 321. The bottom surface 325 of the first plug connection part 322 is partially recessed to form an internal plug connection port 307, i.e., the opening of the internal plug connection port 307 is located on the bottom surface 325 of the first plug connection part 322. The internal plug connection port 307 extends from the bottom surface 325 of the first plug connection part 322 in a direction toward the top surface 323 of the first cover part 321, and passes through the top surface 323 of the first cover part 321. The first cover member 32 is made of an elastic material such as silica gel or TPU.

Figure 16 is a schematic structural diagram of the first cover member 32 shown in Figure 15 cut in the E-E direction.

The internal plug connection port 307 includes an upper end 3071 and a lower end 3072 that are in communication with each other. The upper end 3071 is close to the upper surface 323 of the first cover part 321. The inner diameter of the upper end 3071 gradually expands in the direction from the bottom surface 324 to the upper surface 323 of the first cover part 321, i.e., in the Z direction shown in the figure (which is also the thickness direction of the first cover part 321). In other words, the upper end 3071 has a substantially horn-shaped hollow structure. The lower end 3072 is located below the upper end 3071, and the lower end 3072 has a substantially cylindrical hollow structure.

9, the first cover member 32 is fixed to one side of the main body member 31 and forms a flow passage 306 together with the main body member 31 by enclosing. This simplifies the process of forming the flow passage 306, i.e., the process of forming the bottom cover 30 is simplified, so that the manufacturing cost of the bottom cover 30 is reduced. The material of the first cover member 32 is different from the material of the main body member 31, i.e., the elastic modulus of the first cover member 32 is different from the elastic modulus of the main body member 31. It should be understood that the material of the first cover member 32 may alternatively be the same as the material of the main body member 31, i.e., the elastic modulus of the first cover member 32 may be the same as the elastic modulus of the main body member 31. In this case, the first cover member 32 may also be integrally formed with the main body member 31, which improves the structural strength of the bottom cover 30 and ensures the structural stability of the bottom cover 30.

In this embodiment, the first cover member 32 is fixedly connected to the boss 314 and forms a flow path 306 together with the boss 314. The first cover member 32 having the first internal plug connection port 307 formed therein is fixedly connected to the first boss 314 and forms the first flow path 306 together with the first boss 314. The first cover member 32 having the second internal plug connection port 307 formed therein is fixedly connected to the second boss 314 and forms the second flow path 306 together with the second boss 314.

In the wearable device 1000 illustrated in this implementation example, the boss 314 formed by partially protruding from the upper surface 323 of the main body member 31 forms a flow path 306 together with the first cover member 32. Instead of increasing the overall thickness of the bottom cover 30, it is only necessary to increase the thickness of the bottom cover 30 partially, thereby reducing the manufacturing cost of the bottom cover 30.

In the following, the assembly structure of the first cover member 32 and the boss 314 will be described using the first cover member 32 with the first internal plug connection port 307 formed therein and the first boss 314 as an example. It should be understood that the assembly structure of the first cover member 32 with the second internal plug connection port 307 formed therein and the second boss 314 is substantially the same as the assembly structure of the first cover member 32 with the first internal plug connection port 307 formed therein and the first boss 314. Details will not be repeated below.

Referring to FIG. 13, the first cover member 32 is fixedly attached to the first mounting groove 316. The first cover part 321 is fixedly attached to the first groove body 3161 of the first mounting groove 316. The first cover part 321 covers the openings of the first part 3171 and the second part 3172 of the flow groove 317 to form the first flow path 3061 of the flow path 306. The first plug connection part 322 extends from the first groove body 3161 to the second groove body 3162, so that the internal plug connection port 307 communicates with the third part 3173 of the flow groove 317. The first plug connection part 322 is in close contact with the groove side wall of the second groove body 3162 to cover the opening of the second part 3172 of the flow groove 317 located on the groove side wall of the second groove body 3162 to form the second flow path 3062 of the flow path 306. The first plug connection portion 322 also covers the opening of the third portion 3173 of the flow channel 317, forming the third flow path 3063 of the flow path 306.

11, the fixing member 33 is located on the side of the main body member 31 that is farther from the first cover member 32, i.e., the fixing member 33 is located on the side of the main body member 31 that is closer to the bottom surface 312. The fixing member 33 has a plate-like structure that matches the shape of the assembly groove 319. The fixing member 33 includes an upper surface 331 and a bottom surface 332 that are arranged opposite each other. The bottom surface 332 of the fixing member 33 is partially recessed to form a second fixing hole 333, i.e., the opening of the second fixing hole 333 is located on the bottom surface 332 of the fixing member 33. The second fixing hole 333 extends in a direction from the bottom surface 332 to the top surface 331 of the fixing member 33 and passes through the top surface 331 of the fixing member 33, i.e., the second fixing hole 333 passes through the fixing member 33 in the thickness direction of the fixing member 33. There are two second fixing holes 333, and the two second fixing holes 333 are spaced apart on the edge of the fixing member 33.

Please refer to Figures 14 and 17. Figure 17 is a schematic structural diagram of the assembly of the fixing member 33 and the main body member 31 in the bottom cover 30 shown in Figure 11.

The fixing member 33 is fixed to the side of the main body member 31 that is away from the first cover member 32. That is, the first cover member 32 and the fixing member 33 are fixed to two opposing sides of the main body member 31, respectively. When a user wears the wearable device 1000, the fixing member 33 is positioned facing the user's wrist, and the first cover member 32 is positioned away from the user's wrist.

Specifically, the fixing member 33 is fixedly attached to the assembly groove 319. The fixing member 33 may be locked to the first fixing hole 3192 by passing through the second fixing hole 333 using a fastener such as a screw or a bolt. This realizes a removable attachment of the fixing member 33. In this case, the fixing member 33 covers the opening of the assembly groove 319, and also covers the avoidance groove 3191 and the external plug connection nozzle 310. Furthermore, the bottom surface 332 of the fixing member 33 is flush with the bottom surface 332 of the main body member 31, that is, the bottom surface 332 of the fixing member 33 and the bottom surface 332 of the main body member 31 are located on the same plane, so that when the user wears the wearable device 1000, the joint between the bottom surface 332 of the fixing member 33 and the bottom surface 332 of the main body member 31 contacts the user's wrist without partially protruding, improving the user's usage experience.

Please refer to Figures 4 and 18. Figure 18 is a schematic structural diagram of the watch face 100 shown in Figure 3 cut in the F-F direction.

The peripheral edge of the main body member 31 is connected to the bezel 10, and together with the bezel 10 and the top cover 20, it surrounds the cavity 110 in the watch face. In this case, the top surface 311 of the main body member 31 faces the cavity 110 in the watch face, i.e., the boss 314 is located in the cavity 110 in the watch face. The first cover member 32 is located in the cavity 110 in the watch face, and the fixing member 33 is located outside the watch face 100. Both the first cover member 32 and the boss 314 are located in the cavity 110 in the watch face. This allows the flow path 306 to be formed by fully utilizing the volume of the cavity 110 in the watch face without adding any additional volume outside the watch face 100, facilitating a lightweight and thin design of the watch face 100.

The processor is housed in the watch face cavity 110. The processor may include one or more processing units. For example, the processor may include an Application Processor (AP), a modem processor, a Graphics Processing Unit (GPU), an Image Signal Processor (ISP), a controller, memory, a video codec, a Digital Signal Processor (DSP), a baseband processor, a Neural-network Processing Unit (NPU), and the like. The various processing units may be separate components or may be integrated into one or more processors. The processor may be the brain and command center of the wearable device 1000. The processor can generate operation control signals based on the instruction operation code and the time series signal to complete the control of instruction fetching and instruction execution. In addition, the processor may further include a memory unit configured to store instructions and data. For example, the memory unit of the processor is a cache. The memory may store instructions or data that the processor uses immediately or repeatedly. When the processor needs to use the instruction or data again, the processor may directly retrieve the instruction or data from the memory. This avoids repeated access and reduces the waiting time of the processor, thereby improving system efficiency.

The blood pressure measurement assembly 40 is electrically connected to the processor. In this embodiment, the blood pressure measurement assembly 40 includes an air pump 41 and a pressure sensor 42. The air pump 41 is electrically connected to the processor and configured to receive a control signal sent by the processor and to suck or expel air based on the control signal. The pressure sensor 42 is spaced apart from the air pump 41 and electrically connected to the processor. The pressure sensor 42 is configured to receive a control signal sent by the processor and to detect a pressure signal based on the control signal and convert the pressure signal into an electrical signal. The pressure sensor may be a capacitive pressure sensor. The capacitive pressure sensor includes at least two parallel plates made of a conductive material. When a force is applied to the pressure sensor, the capacitance between the electrodes changes. The processor determines the pressure intensity based on the change in capacitance between the electrodes. Of course, the pressure sensor 42 may alternatively be a resistive pressure sensor, an electromagnetic induction pressure sensor, etc.

Specifically, the blood pressure measurement assembly 40 is located in the cavity 110 in the watch face, and the air nozzle 401 of the blood pressure measurement assembly 40 is in communication with the internal plug connection port 307. The air nozzle 401 of the air pump 41 is in communication with the first internal plug connection port 307, so that the air pump 41 sends the air sucked in through the air vent 109 to the first flow path 306, or receives air sent from the first flow path 306 and discharges the air through the air vent 109. The air nozzle 401 of the pressure sensor 42 is in communication with the second internal plug connection port 307, so that the pressure sensor 42 detects pressure changes through the second flow path 306 to measure blood pressure.

In the following, the assembly structure of the air nozzle 401 of the blood pressure measurement assembly 40 and the internal plug connection port 307 is described using the air nozzle 401 of the air pump 41 as an example. The air nozzle 401 of the blood pressure measurement assembly 40 referred to below refers to the air nozzle 401 of the air pump 41, and the internal plug connection port 307 referred to below refers to the first internal plug connection port 307 which is mutually connected to the air nozzle 401 of the air pump 41. Please note that the assembly structure of the air nozzle 402 of the pressure sensor 42 and the second internal plug connection port 307 is substantially the same as the assembly structure of the air nozzle 401 of the air pump 41 and the first internal plug connection port 307, so the details will not be repeated below.

In this embodiment, the air nozzle 401 of the blood pressure measurement assembly 40 is plugged into the internal plug connection port 307 and extends in the Z direction. The air nozzle 401 of the blood pressure measurement assembly 40 is plugged into the internal plug connection port 307 from the upper end of the internal plug connection port 307. Since the inner diameter of the upper end of the internal plug connection port 307 gradually expands in the Z direction, the air nozzle 401 of the blood pressure measurement assembly 40 can be easily plugged into the internal plug connection port 307. In addition, the inner diameter of the lower end of the internal plug connection port 307 is slightly smaller than or equal to the outer diameter of the air nozzle 401 of the blood pressure measurement assembly 40, so that when the air nozzle 401 of the blood pressure measurement assembly 40 extends from the upper end to the lower end of the internal plug connection port 307, the air nozzle 401 of the blood pressure measurement assembly 40 is reliably in close contact with the first cover member 32, thereby ensuring the connection reliability between the air nozzle 401 of the blood pressure measurement assembly 40 and the first cover member 32.

It should be understood that in another embodiment, the manner of forming the internal plug connection port 307 may be the same as the manner of forming the external plug connection port 305. In this case, the upper surface 323 of the first cover part 321 partially protrudes to form an internal plug connection nozzle, and the internal plug connection port 307 is formed inside the internal plug connection nozzle. The air nozzle 401 of the blood pressure measurement assembly 40 and the internal plug connection nozzle are plugged together, specifically, the air nozzle 401 of the blood pressure measurement assembly 40 is plugged into the internal plug connection port 307, or the air nozzle 401 of the blood pressure measurement assembly 40 is sleeved with the internal plug connection nozzle.

In one implementation example, the elasticity coefficient of the air nozzle 401 of the blood pressure measurement assembly 40 is greater than the elasticity coefficient of the first cover member 32. That is, the air nozzle 401 of the blood pressure measurement assembly 40 is made of a hard material, and the first cover member 32 is made of an elastic material. Specifically, the air nozzle 401 of the blood pressure measurement assembly 40 is made of a relatively hard material, and the first cover member 32 is made of a relatively soft material. When the air nozzle 401 of the blood pressure measurement assembly 40 is inserted into the internal plug connection port 307, the first cover member 32 is deformed when pressed by the air nozzle 401 of the blood pressure measurement assembly 40 and tightly fits the air nozzle 401 of the blood pressure measurement assembly 40, thereby ensuring airtightness between the air nozzle 401 of the blood pressure measurement assembly 40 and the first cover member 32. It should be understood that sealing may also be performed between the air nozzle 401 of the blood pressure measurement assembly 40 and the first cover member 32 using a structure such as a sealing ring or a sealing gasket. This is not particularly limited in the present application.

The sensor assembly is spaced apart from the blood pressure measurement assembly 40 and is electrically connected to the processor. Specifically, the sensor assembly includes a heart rate detection sensor, which faces directly or is at least partially housed in a mounting hole (not shown). The heart rate detection sensor is an optical heart rate sensor. When a user wears the wearable device 100, the bottom surface 312b of the boss 312a is in close contact with the user's wrist, and the optical heart rate sensor can send a heart rate detection signal through the mounting hole. This allows accurate heart rate detection to be achieved, thereby improving the functional diversity of the wearable device 1000 and improving the user's usage experience. Of course, the heart rate detection sensor may alternatively be a sensor such as a bone conduction sensor capable of detecting heart rate.

In addition, the sensor assembly may further include sensors such as a gyroscope sensor, a barometric pressure sensor, an acceleration sensor, a distance sensor, an optical proximity sensor, a fingerprint sensor, a temperature sensor, or an ambient light sensor, which may further enhance the functional diversity of the wearable device 1000 and improve the user's experience.

Please refer to Figures 2 and 19. Figure 19 is a schematic structural diagram of the compression band 300 in the wearable device 1000 shown in Figure 2.

The compression band 300 is located on one side of the watch face 100. The compression band 300 includes a cuff 320, an air bag (not shown) housed in the cuff 320, and an air nozzle 340 in communication with the air bag. The cuff 320 includes an upper surface 320a and a bottom surface 320b arranged opposite each other, and a peripheral surface 320c connected between the upper surface 320a and the bottom surface 320b. The air bag is located at a position of the cuff 320 close to the watch face 100. The air nozzle 340 protrudes from the upper surface 320a of the cuff 320. The air nozzle 340 extends from the upper surface 320a of the cuff 320 in a direction away from the bottom surface 320b, i.e., the air nozzle 340 extends in the Z direction. The material of the air nozzle 340 may be the same as the material of the air bag. In this case, the air nozzle 340 may be formed integrally with the air bag. Alternatively, the material of the air nozzle 340 may be different from the material of the air bladder. In this case, the air nozzle 340 may be formed so as to be removable together with the air bladder by assembly.

In this embodiment, there are two air nozzles 340. The two air nozzles 340 are a first air nozzle 340 and a second air nozzle 340, and the first air nozzle 340 and the second air nozzle 340 are spaced apart in the X direction. The structures of the first air nozzle 340 and the second air nozzle 340 are basically the same.

Figure 20 is a schematic structural diagram of the assembly of the compression band 300 and the watch face 100 in the wearable device 1000 shown in Figure 2. Figure 21a is a schematic structural diagram of the structure shown in Figure 20 cut in the G-G direction. Both Figures 20 and 21a show only the portion where the compression band 300 is connected to the watch face 100.

The compression band 300 extends partially into the assembly groove 319, is fixed to the assembly groove 319, and extends partially outward from the assembly groove 319. In this case, the compression band 300 shares the entire thickness distance of the bottom cover 30 in the Z direction, which reduces the effect on the thickness of the wearable device 1000 caused by assembling the compression band 300 to the bottom cover 30, facilitating the realization of a lightweight and thin design for the wearable device 1000.

The air nozzle 340 of the compression band 300 is located in the assembly groove 319. Specifically, the air nozzle 340 of the compression band 300 is mutually connected to the external plug connection port 305. That is, the air nozzle 340 of the compression band 300 is connected to the air nozzle 401 of the blood pressure measurement assembly 40 through the flow path 306. In this case, the air bag 330 of the compression band 300 is connected to the external plug connection port 305 through the air nozzle 340. That is, the air bag 330 of the compression band 300 is connected to the air nozzle 401 of the blood pressure measurement assembly 40 through the air nozzle 340 and the flow path 305 of the compression band 300.

The cross-sectional area of the flow passage 306 is greater than or equal to 1 ^mm2 , i.e., the inner diameter of the flow passage 306 is sufficiently large, so that the resistance generated when the air flows inside the flow passage 306 is relatively small. This ensures that the air exchange speed between the air nozzle 340 of the compression band 300 and the air nozzle 401 of the blood pressure detection assembly 40 is sufficiently high, which promotes high-speed air circulation between the air nozzle 340 of the compression band 300 and the air nozzle 401 of the blood pressure detection assembly 40, and improves the blood pressure detection efficiency of the wearable device 1000.

In the wearable device 1000 illustrated in this embodiment, the flow path 306 separates the air nozzle 340 of the compression band 300 from the air nozzle 401 of the blood pressure measurement assembly 40, and the blood pressure measurement assembly 40 is not easily affected and displaced during the process of assembling or disassembling the compression band 300. This helps to extend the service life of the wearable device 1000 by avoiding the problem of the blood pressure measurement assembly 40 being damaged when the compression band 300 moves.

Furthermore, since the external plug connection port 305, the flow path 306, and the internal plug connection port 307 are all integrated in the bottom cover 30 of the watch face 100, there is no need to place a communication pipe in the watch face cavity 110 between the air nozzle 340 of the compression band 300 and the air nozzle 340 of the blood pressure measurement assembly 40. This avoids the space usage of the communication pipe in the watch face cavity 110, promotes the expansion of the space utilization of the watch face cavity 110, realizes a lightweight and thin design of the watch face 100, and improves the elegance of the appearance of the wearable device 1000.

Furthermore, the external plug connection port 305 communicating with the air nozzle 340 of the compression band 300 is closer to the bezel 10, i.e., the internal plug connection port 307 communicating with the air nozzle 401 of the blood pressure measurement assembly 40 is closer to the center of the bottom cover 30. In this way, the air nozzle 340 of the compression band 300 can communicate with the air nozzle 401 of the blood pressure measurement assembly 40 without extending directly under the blood pressure measurement assembly 40. The extension length of the compression band 300 under the watch face 100 can be reduced, which promotes the reduction of the overall thickness of the wearable device 1000 and the realization of a lightweight and thin design of the wearable device 1000. Furthermore, the position between the compression band 300 and the blood pressure measurement assembly 40 can be designed more flexibly, and the position of functional components such as a battery and/or a sensor module located in the cavity 110 in the watch face can be designed more flexibly. This promotes greater spatial utilization of the cavity 110 within the watch face, realizing a lightweight and thin design for the wearable device 1000.

Please refer to Figures 21a and 21b. Figure 21b is an enlarged schematic diagram of region H in the structure shown in Figure 21a.

In this embodiment, the first air nozzle 340 of the compression band 300 is mutually connected to the first external plug connection port 305. In this case, the first air nozzle 340 of the compression band 300 is connected to the air nozzle 401 of the air pump 41 through the first flow path 306. When it is necessary to perform blood pressure measurement with the wearable device 1000, the air pump 41 can use the first flow path 306 and the air nozzle 340 of the compression band 300 to send the outside air sucked through the ventilation hole 109 to the air bag 330 of the compression band 300, thereby inflating the air bag 330 of the compression band 300. When the blood pressure measurement with the wearable device 1000 is completed, the air in the air bag 330 of the compression band 300 may be sent to the air pump 41 through the air nozzle 340 and the first flow path 306 of the compression band 300, and the air pump 41 can discharge this air through the ventilation hole 109. The air flow path when the air pump 41 inflates the air bag 330 is shown by the dashed arrow in FIG. 21b. The air flow path when the air pump 41 expels the air in the air bag 330 is shown by the solid arrow in FIG. 21b. The explanations of the solid and dashed arrows in the following attached figures are to be understood in the same way.

The second air nozzle 340 of the compression band 300 is in communication with the second external plug connection port 305. In this case, the second air nozzle 340 of the compression band 300 is in communication with the air nozzle 401 of the pressure sensor 42 through the second flow path 306. The pressure sensor 42 can detect the pressure value inside the air bag 330 of the compression band 300 through the second flow path 306.

In the wearable device 1000 illustrated in this embodiment, the air nozzle 401 of the air pump 41 and the pressure sensor 42 each communicate with the air nozzle 340 of the compression band 300 through two flow paths 306, rather than sharing one flow path. This not only improves the mounting flexibility of the blood pressure measurement assembly 40 in the cavity 110 in the watch face, but also prevents air transmission between the air pump 41 and the air bag 330 of the compression band 300 and between the pressure sensor 42 and the air bag 330 of the compression band 300 from interfering with each other, thereby promoting improvement of the measurement sensitivity and measurement accuracy of the blood pressure measurement assembly 40 in the blood pressure measurement process.

In the following, the assembly structure of the first air nozzle 340 and the first external plug connection nozzle 310 of the compression band 30 is used as an example to provide an explanation. The air nozzle 340 of the compression band 300 referred to below refers to the first air nozzle 340 of the compression band 340, and the external plug connection nozzle 310 referred to below refers to the first external plug connection nozzle 310. It should be understood that the assembly structure of the second air nozzle 340 and the second external plug connection nozzle 310 of the compression band 300 is basically the same as the assembly structure of the first air nozzle 340 and the first external plug connection nozzle 310, so the details will not be repeated below.

Specifically, the air nozzle 340 of the compression band 300 is connected to the external plug connection nozzle 310 by a sleeve, i.e., the external plug connection nozzle 310 is plugged into the air nozzle 340 of the compression band 300, thereby connecting the compression band 300 and the bottom cover 30 to each other. Since the inner diameter of the air nozzle 340 of the compression band 300 is slightly smaller than the outer diameter of the external plug connection nozzle 310, when the air nozzle 340 of the compression band 300 is connected to the external plug connection nozzle 310 by a sleeve, i.e., when the external plug connection nozzle 310 is plugged into the air nozzle 340 of the compression band 300, the air nozzle 340 of the compression band 300 can be tightly attached to the external plug connection nozzle 310, so that the connection reliability between the air nozzle 340 of the compression band 300 and the external plug connection nozzle 310 is ensured.

Compared to an embodiment in which the second distance range [Z21, Z22] completely overlaps with the first distance range [Z11, Z12], in the wearable device 1000 illustrated in this embodiment, the length of the external plug connection nozzle 310 in the Z direction is long, and the area of the outer circumferential surface of the external plug connection nozzle 310 is also large, so it can be seen that the contact area between the air nozzle 340 of the compression band 300 and the external plug connection nozzle 310 is also large. This not only improves the connection reliability between the air nozzle 340 of the compression band 300 and the external plug connection nozzle 310, but also reduces the risk of air leakage between the air nozzle 340 of the compression band 300 and the external plug connection nozzle 310.

In one implementation example, the elastic modulus of the main body member 31 is greater than the elastic modulus of the air nozzle 340 of the compression band 300. That is, the main body member 31 is made of a hard material, and the air nozzle 340 of the compression band 300 is made of an elastic material. Specifically, the external plug connection nozzle 310 of the main body member 31 is made of a relatively hard material, and the air nozzle 340 of the compression band 300 is made of a relatively soft material. When the external plug connection nozzle 310 is inserted into the air nozzle 340 of the compression band 300, since the external plug connection nozzle 310 is relatively hard and the air nozzle 340 of the compression band 300 is relatively soft, when the air nozzle 340 of the compression band 300 is pushed in by the external plug connection nozzle 310, it deforms and fits snugly against the external plug connection nozzle 310, ensuring airtightness between the external plug connection nozzle 310 and the air nozzle 340 of the compression band 300. It is understood that sealing may also be performed between the air nozzle 340 of the compression band 300 and the external plug connection nozzle 310 using a sealing ring or sealing gasket. This is not particularly limited in the present application.

The air nozzle 340 of the compression band 300 extends partially into the avoidance groove 3191. The inner diameter of the avoidance groove 3191 is greater than or equal to the outer diameter of the air nozzle 340 of the compression band 300, so that the air nozzle 340 of the compression band 300 is inserted into the avoidance groove 3191 and avoided, and the influence of the assembled structure of the air nozzle 340 of the compression band 300 and the external plug connection nozzle 310 on the thickness of the wearable device 1000 is suppressed, thereby facilitating the realization of a lightweight and thin design of the wearable device 1000. It should be understood that the air nozzle 340 of the compression band 300 may be completely accommodated in the avoidance groove 3191. In this case, the external plug connection nozzle 310 only needs to extend from the bottom groove wall of the assembly groove 319 so as not to protrude. This can further suppress the influence of the assembled structure of the air nozzle 340 of the compression band 300 and the external plug connection nozzle 310 on the thickness of the wearable device 1000.

The fixing member 33 is fixed to the side of the compression band 300 that is away from the main body member 31 and is in contact with the compression band 300. This not only prevents the air nozzle 340 of the compression band 300 from coming off the external plug connection nozzle 310, thereby maintaining the plug connection stability between the air nozzle 340 of the compression band 300 and the external plug connection nozzle 310, but also prevents the compression band 300 from coming off the assembly groove 319, improving the assembly stability between the compression band 300 and the bottom cover 30.

In the wearable device 1000 illustrated in this embodiment, the blood pressure measurement assembly 40 is integrated into the watch face 100, and a compression band 300 with a stacked watch band 200 is added. By wearing the wearable device 1000 on the user's wrist, the user can measure blood pressure anytime and anywhere. Since the user's blood pressure status can be grasped at the appropriate time without using an additional blood pressure monitor for blood pressure measurement, the user's convenience in blood pressure measurement is improved, and the user's usage experience is improved.

When the wearable device 1000 is worn on the user's wrist, the compression band 300 fits closely to the user's wrist. When the wearable device 1000 receives a blood pressure measurement command input, the processor sends a blood pressure measurement signal to the air pump 41 and the pressure sensor 42. The air pump 41 draws in air from the external environment through the air vent 109 and inflates and pressurizes the air bag 330 of the compression band 300 through the first flow path 306 and the first air nozzle 340 of the compression band 300. In this case, the compression band 300 inflates and compresses the wrist artery of the user. The pressure sensor 42 detects the pressure value in the air bag 330 of the compression band 300 using the second flow path 306 and the second air nozzle 340 of the compression band 300, and feeds back this pressure value to the processor in real time. The processor determines whether the pressure value in the air bag 330 of the compression band 300 meets the requirements for blood pressure measurement. If the requirements are not met, the processor continues to send blood pressure measurement signals to the air pump 41, and the air pump 41 continues to inflate and pressurize the air bladder 330 of the compression band 300, until the processor determines that the pressure value fed back by the pressure sensor 42 meets the requirements for blood pressure measurement. The processor calculates the user's blood pressure based on the pressure value fed back in real time by the pressure sensor 42, and displays and feeds back the blood pressure to the user using the display. After the blood pressure measurement is completed, the processor stops sending blood pressure measurement signals, and both the air pump 41 and the pressure sensor 42 stop operating. Air in the air bladder 330 of the compression band 300 is sent to the air pump 41 through the first air nozzle 340 and the first flow path 306 of the compression band 300. The air pump 41 exhausts the air through the air vent 109. At this point, the compression band 300 returns to a flat state and fits tightly around the user's wrist.

Figure 22 is a schematic cross-sectional structural diagram of the bottom cover 30 in the second wearable device 1000 according to one embodiment of the present application, taken along the CC direction. Figure 23 is a schematic partial structural diagram of the front view of the structure shown in Figure 22.

The difference between the wearable device 1000 illustrated in this embodiment and the wearable device 1000 illustrated in the previous embodiment is that the external plug connection port 305 and the internal plug connection port 307 are located on two opposite sides of the upper surface 301 of the bottom cover 30, respectively. Specifically, the external plug connection port 305 is located below the upper surface 301 of the bottom cover 30, and a first distance range [Z11, Z12] is formed between the external plug connection port 305 and the upper surface 301 of the bottom cover 30, where Z11<Z12<0. The internal plug connection port 307 is located above the upper surface 301 of the bottom cover 30, and a second distance range [Z21, Z22] is formed between the internal plug connection port 307 and the upper surface 301 of the bottom cover, where 0<Z21<Z22.

In this case, the first distance range [Z11, Z12] does not overlap with the second distance range [Z21, Z22]. That is, the external plug connection port 305 and the internal plug connection port 307 are completely staggered in the direction from the central axis O1 of the external plug connection port 305 to the central axis O2 of the internal plug connection port 307. In other words, the external plug connection port 305 and the internal plug connection port 307 do not share the thickness distance in the Z direction of the bottom cover 30.

The flow path 306 is hyphen-shaped and parallel to the XY plane. A third distance range [Z31, Z32] is formed between the flow path 306 and the upper surface 301 of the bottom cover 30. Specifically, the lower end surface of the flow path 306 is flush with the upper port of the external plug connection port 305, i.e., Z31=Z12. The upper end surface of the flow path 306 is flush with the lower port of the internal plug connection port 307, i.e., Z32=Z21. In this case, only both end points of the third distance range [Z31, Z32] are located in a combination set of the second distance range [Z21, Z22] and the first distance range [Z11, Z12]. That is, the flow path 306 is staggered from both the external plug connection port 305 and the internal plug connection port 306 in the direction from the central axis O1 of the external plug connection port 305 to the central axis O2 of the internal plug connection port 307. In the wearable device 1000 illustrated in this embodiment, it can be seen that the structures of the external plug connection port 305, the flow path 306, and the internal plug connection port 306 are simple. This simplifies the process of forming the bottom cover 30, and further reduces the manufacturing cost of the bottom cover 30.

Figure 24 is a schematic structural diagram of the main body member 31 of the bottom cover 30 of the third wearable device 1000 according to one embodiment of the present application, cut in the D-D direction.

The difference between the wearable device 1000 provided in this embodiment of the present application and the wearable device 1000 exemplified in the two previous embodiments is that the bottom surface 312 of the main body member 31 is partially recessed to form the second mounting groove 3121, and the second mounting groove 3121 is connected to the flow groove 317. Specifically, the bottom groove wall of the assembly groove 319 is partially recessed to form the second mounting groove 3121. That is, the opening of the second mounting groove 3121 is located in the bottom groove wall of the assembly groove 319. The second mounting groove 3121 is recessed in the direction from the bottom groove wall of the assembly groove 319 to the upper surface 315 of the boss 314 and passes through the bottom groove wall of the flow groove 317.

Figure 25 is a schematic structural diagram of the bottom cover 30 of the third wearable device 1000 according to one embodiment of the present application, cut in the CC direction.

In this embodiment, the bottom cover 30 further includes a second cover member 34, which is located on the side of the main body member 31 away from the first cover member 32, and the second cover member 34 forms an external plug connection port 305. The second cover member 34 includes a second cover portion 341 and a second plug connection portion 342 connected to the second cover portion 341. The first cover portion 321 has a substantially flat plate-like structure. The second cover portion 341 includes an upper surface and a bottom surface that are arranged opposite each other. The second plug connection portion 342 is connected to the upper surface of the second cover portion 341. The second plug connection portion 342 extends from the upper surface of the second cover portion 341 in a direction away from the bottom surface and has a substantially circular tubular structure. The second plug connection portion 342 includes an upper surface that has the same orientation as the upper surface of the second cover portion 341. The upper surface of the second plug connection portion 342 is partially recessed to form an external plug connection port 305, i.e., the opening of the external plug connection port 305 is located on the upper surface of the second plug connection portion 342. The external plug connection port 305 extends from the upper surface of the second plug connection portion 342 to the bottom surface of the second cover portion 341, and passes through the bottom surface of the second cover portion 341. The second cover member 34 is made of an elastic material such as silica gel or TPU.

The second fixing member is fixed to the side of the main body member 31 away from the first cover member 32. Specifically, the second cover member 34 is fixed to the assembly groove 319 and is located between the main body member 31 and the fixing member 33. The second cover member 34 may be removably attached to the assembly groove 319. The second cover portion 341 of the second cover member 34 is fixed to the assembly groove 319, and the second plug connection portion 342 extends into the second mounting groove 3121, so that the external plug connection port 305 communicates with the flow path 306.

Figure 26 is a schematic structural diagram of an assembly of the bottom cover 30 and the compression band 300 in a third wearable device 1000 according to one embodiment of the present application. Figure 27 is a schematic structural diagram of the structure shown in Figure 26 cut in the II direction.

The air nozzle 340 of the compression band 300 is plugged into the external plug connection port 305, and is connected to the external plug connection port 305. The outer diameter of the air nozzle 340 of the compression band 300 is slightly larger than the inner diameter of the external plug connection port 305, so that the air nozzle 340 of the compression band 300 and the second cover member 34 are tightly and reliably attached to each other, ensuring the reliability of the connection between the air nozzle 340 of the compression band 300 and the second cover member 34.

In one implementation example, the elastic modulus of the air nozzle 340 of the compression band 300 is greater than the elastic modulus of the second cover member 34. That is, the air nozzle 340 of the compression band 300 is made of a hard material, and the second cover member 34 is made of an elastic material. Specifically, the air nozzle 340 of the compression band 300 is made of a relatively hard material, and the second cover member 34 is made of a relatively soft material. When the air nozzle 340 of the compression band 300 is inserted into the external plug connection port 305, the second cover member 34 is deformed when pressed by the air nozzle 340 of the compression band 300 and tightly fits the air nozzle 340 of the compression band 300, ensuring airtightness between the air nozzle 340 of the compression band 300 and the second cover member 34.

In the wearable device 1000 illustrated in this embodiment, the second cover member 34 is used to form the external plug connection port 305, and the air nozzle 340 of the compression band 300 is plugged into the external plug connection port 305 to realize a mutual plug connection to the external plug connection port 305. Compared with an embodiment in which the air nozzle 340 of the compression band 300 is connected to the external plug connection nozzle 310 by a sleeve, this embodiment avoids the problem that the air nozzle 340 of the compression band 300 cannot be plugged into the external plug connection nozzle 310 due to the processing error of the air nozzle 340 of the compression band 300. This reduces the requirements for the processing accuracy of the air nozzle 340 of the compression band 300, promotes the reduction of the manufacturing cost of the compression band 300, and improves the product competitiveness of the wearable device 1000.

Figure 28 is a schematic structural diagram of the bottom cover 30 of the fourth wearable device 1000 according to one embodiment of the present application, cut in the CC direction.

The difference between the wearable device 1000 illustrated in this embodiment of the present application and the wearable device 1000 illustrated in the second embodiment described above is that the peripheral surface 313 of the main body member 31 partially protrudes to form an external plug connection nozzle 310, and an external plug connection port 305 is formed inside the external plug connection nozzle 310. The external plug connection nozzle 310 extends from the peripheral surface 313 of the main body member 31 along the X-Y plane.

Figure 29 is a schematic structural diagram of the compression band 300 in the fourth wearable device 1000 according to one embodiment of the present application. Figure 30 is a schematic structural diagram of the assembled structure of the compression band 300 and the bottom cover 30 in the fourth wearable device 1000 according to one embodiment of the present application, cut in the II direction.

The air nozzle 340 of the compression band 300 is sleeved with the external plug connection nozzle 310, i.e., the external plug connection nozzle 310 is plugged into the air nozzle of the compression band 300. The air nozzle 340 of the compression band 300 protrudes from the peripheral surface 320c of the cuff 320. The air nozzle 340 of the compression band 300 extends from the peripheral surface 320 of the cuff 320 along the X-Y plane.

In the wearable device 1000 illustrated in this embodiment, the compression band 300 is connected to the peripheral surface 313 of the main body member 31. In this case, the compression band 300 does not occupy the bottom surface space of the bottom cover 30, but only shares some or all of the thickness distance of the bottom cover 30 in the Z direction. This reduces the effect of the presence of the compression band 300 on the thickness of the wearable device 1000, making it easier to design the wearable device 1000 in a lightweight and thin form.

Figure 31 is a schematic exploded structural diagram of a fifth wearable device 1000 according to one embodiment of the present application. Figure 32 is a schematic exploded structural diagram of a watch face 100 in the wearable device 1000 shown in Figure 31.

The difference between the wearable device 100 illustrated in this embodiment and the four wearable devices 1000 described above is that the blood pressure measurement component 40 is a component incorporating the functions of an air pump and a pressure sensor, that is, both the air pump and the pressure sensor are incorporated into the blood pressure measurement component 40 to simplify the structure of the blood pressure measurement assembly 40 and reduce the volume occupied by the blood pressure measurement assembly 40 in the cavity inside the watch face, facilitating a lightweight and thin design of the watch face 200. There is one external plug connection port, one flow path, and one internal plug connection port. The air nozzle of the blood pressure measurement component 40 is in communication with the internal plug connection port, and the air nozzle 340 of the compression band 300 is in communication with the internal plug connection port. In this case, there is also one air nozzle 340 of the compression band 300.

It should be understood that in the wearable device 1000 illustrated in this embodiment, components such as the bezel 10 and top cover 20 of the watch face 100, as well as other structures of the watch band 200 and compression band 300, are essentially the same as the structures of the wearable device 1000 illustrated in the four previous embodiments. Details will not be described here.

Figure 33 is a partial schematic structural diagram of an assembly structure of a watch face 100 and a compression band 300 in a sixth wearable device according to one embodiment of the present application, cut in the G-G direction.

The difference between the wearable device 100 illustrated in this embodiment and the five wearable devices 100 described above is that the sensor assembly further includes an air sensor 50, which is located in the flow path 306. Specifically, the air sensor 50 is fixed to the inner wall of the flow path 306 and is electrically connected to the processor. As a result, when the wearable device 1000 performs blood pressure measurement, air components such as formaldehyde, oxygen, or carbon dioxide present in the surrounding environment of the wearable device 1000 are analyzed, thereby improving the functional diversity of the wearable device 1000 and improving the user's usage experience.

Specifically, when the wearable device 1000 performs blood pressure measurement, the air pump 41 draws air from the surrounding environment and fills the air bladder 330 of the compression band 300 with air through the flow path 306 and the air nozzle 340 of the compression band 300 to perform blood pressure measurement. Because the air sensor 50 is located inside the flow path 306, air flows through the air sensor 50. When the pressure sensor measures the pressure value P in the air bladder 33 of the compression band 300 at a certain time, the air sensor 50 simultaneously analyzes the concentration value C of the air that needs to be measured. The processor receives the pressure value P fed back by the pressure sensor and the air concentration value C fed back by the air sensor 50, processes the pressure value P and the concentration value C, and obtains the concentration of air measured in the environment.

The above description is merely a specific implementation example of the present application, and is not intended to limit the scope of protection of the present application. Any modifications or replacements that a person skilled in the art can easily conceive within the technical scope disclosed in the present application shall be included in the scope of protection of the present application. Therefore, the scope of protection of the present application shall be subject to the scope of protection of the claims.
